The beneficial effects of the utility model are:
The effect and advantage of the utility model are to connect sliding block by tension spring respectively by making sliding block match to merge with sliding slot
It connects in the two sides of the protrusion of pedestal, in this way when pressure reductor bears the shock from errant vehicle, pressure reductor can be deformed
And the sliding block being connected is pushed to move respectively to the upper and lower part of column, at this point, tension spring is by preventing sliding block far from pedestal
The mode of protrusion realizes the buffering to impact force, and the damping spring between pressure reductor and pedestal, which is arranged in, can also pass through resistance
Only pressure reductor realizes the buffering to impact force close to the mode of pedestal, and finally the connection unit of the device can also be liquidated by deformation
Power is hit to be buffered.The highway anticollision device, collision-prevention device can effectively absorb the impact force of errant vehicle, hard so as to reduce
Property knockout process in excessive damage that vehicle is generated, meanwhile, can also prevent safeguard structure excessive deformation or with column phase point
From.
